Cyntec CMME and CMMS Magnetic Components: Model Guide
Cyntec CMME and CMMS Magnetic Components: Model Guide
Cyntec CMME and CMMS magnetic components are part numbers worth checking when sourcing inductors and power magnetic components for electronic designs. Selecting the correct model requires more than matching the series prefix: engineers must verify inductance, DC resistance (DCR), saturation current, temperature rise and package dimensions against the manufacturer's datasheet.
This guide explains how to identify CMME and CMMS part numbers, compare electrical and mechanical specifications, evaluate replacement candidates and prepare an accurate quotation request.
1. What Should You Check When Selecting Cyntec CMME and CMMS Components?
Before choosing a component, confirm its exact part number and the corresponding manufacturer documentation.
Inductance: Confirm the nominal inductance and tolerance required by the circuit.
DC resistance (DCR): Check winding resistance and its effect on conduction losses.
Saturation current (Isat): Ensure the component can handle peak current without unacceptable inductance reduction.
Heating-rated current (Idc): Verify the current rating under the manufacturer's specified temperature-rise conditions.
Dimensions: Confirm length, width, height and PCB land pattern.
Operating conditions: Review temperature, switching frequency and thermal derating requirements.
These parameters are especially important when selecting power chokes for DC-DC converters, voltage regulator modules and embedded power supplies.
2. CMME vs CMMS: How to Compare the Models
The CMME and CMMS prefixes should be treated as distinct part-number identifiers until their exact product specifications have been verified. Do not assume that the two prefixes represent identical constructions or interchangeable components.
| Comparison Item | What to Verify |
|---|---|
| Series and Construction | Confirm the official product family and magnetic structure. |
| Inductance | Compare nominal value, tolerance and measurement conditions. |
| DCR | Compare maximum resistance and associated test conditions. |
| Saturation Current | Check the inductance-drop criterion and operating temperature. |
| Heating-Rated Current | Compare temperature-rise limits and PCB conditions. |
| Package Dimensions | Verify body dimensions, height and recommended land pattern. |
| Part Number Suffixes | Confirm tolerance, electrical options and ordering details using the official documentation. |
Important: A similar-looking part number does not prove electrical or mechanical compatibility. Obtain the correct Cyntec datasheet before approving a CMME-to-CMMS substitution.
3. Example Cyntec Part Numbers to Verify
The following part numbers have appeared in sourcing records and can be used as starting points for manufacturer-document verification.
| Part Number | Recommended Verification |
|---|---|
| CMME063T-R47MS-59 | Confirm inductance, DCR, current ratings and package drawing. |
| CMMS063T-R10MS-59 | Confirm the exact series, electrical characteristics and suffix definition. |
| CMME104T-R22MS0R607 | Verify the complete ordering code and applicable datasheet revision. |
| CMMS053T-2R2MS-72 | Confirm inductance, tolerance, current capability and dimensions. |
The complete part number should be checked against Cyntec's official product database or a manufacturer-approved document. The suffixes shown above should not be decoded by assumption.
4. How to Select a Cyntec Power Choke
Inductance and Circuit Requirements
Start with the inductance specified by the power-converter design. A different inductance value can change current ripple, transient response and converter stability.
DCR and Power Loss
Lower DCR generally reduces winding conduction loss. For a simplified DC winding-loss estimate:
Ploss = IRMS2 × DCR
For example, a 10A RMS current through a 2mΩ winding produces approximately 0.2W of DC resistance loss. Actual total inductor loss also includes core and AC winding losses.
Saturation Current and Heating Current
Isat and Idc describe different limitations. Saturation current relates to the reduction of inductance under current, while heating-rated current relates to temperature rise under defined test conditions.
For switching power supplies, check both values against peak and RMS current respectively. Neither rating should be used alone to establish the allowable operating current.
Package and PCB Layout
Verify the component's dimensions, height clearance, recommended PCB footprint and thermal conditions. A component with similar inductance may still be unsuitable if its mounting geometry or current capability differs.
5. Can a CMME Component Replace a CMMS Component?
Not without verification. A potential replacement must meet the electrical, mechanical and thermal requirements of the original design.
Confirm nominal inductance and tolerance.
Compare maximum DCR and saturation-current characteristics.
Check heating-rated current and temperature rise.
Verify dimensions, terminal configuration and PCB footprint.
Review impedance and loss behavior at the actual switching frequency.
Validate converter ripple, transient response and temperature under operating load.
If the original datasheet is unavailable, provide the complete part number and any existing component markings to the supplier for identification. Do not approve a replacement based only on a similar series prefix.
6. Official Cyntec Technical Resources
Use Cyntec's official resources to confirm the exact product specification before making a design or purchasing decision.
Cyntec Official Website – Manufacturer product information and technical resources.
Cyntec Product Portfolio – Explore the manufacturer's product families.
Cyntec Parameter Search – Search power chokes by dimensions, inductance, DCR and current ratings where supported.
Cyntec Product Catalog (PDF) – Review published component families and electrical specifications.
Not every CMME or CMMS ordering code is necessarily covered by the same catalog revision. Confirm the exact model and current document before relying on a listed specification.
