Cyntec TLM966411F, TLM966413F and TLM104613F are four-terminal TLVR trans-inductors designed for AI servers, GPUs, CPUs, FPGAs and high-performance network equipment.

All three series support fast load-transient response in multiphase voltage regulators, but they differ in inductance range, DCR, current capability and package dimensions. The correct choice depends primarily on available PCB space, required saturation current and acceptable power loss.

Main Specifications Comparison

Available Models

TLM966411F: Lower DCR and Lower Height

TLM966411F is generally the preferred option when efficiency and component height are the main design constraints. It has the lowest primary and secondary DCR of the three series, helping reduce winding losses in high-current operation.

It also provides the highest primary and secondary rated current and is the only compared series offering a 180nH version. Typical applications include GPU and CPU multiphase power rails where low conduction loss is more important than maximum saturation current.

TLM966413F: Higher Saturation Current

TLM966413F uses the same length and width as TLM966411F but has a taller package. The additional height supports higher saturation-current performance, particularly in the common 120nH and 150nH versions.

This series is suitable for power rails with large peak-current requirements and severe transient loads. Designers must confirm that the available vertical space can accommodate the taller component.

TLM104613F: Narrower PCB Footprint

TLM104613F has the narrowest package of the three series and includes a 90nH option. It is useful when the power stage has limited board width or when inductors must be placed closely around a processor or accelerator.

The trade-off is higher winding resistance and lower secondary rated current. Thermal performance and power loss should therefore be checked carefully at the expected operating current.

Frequently Asked Questions

Which series has the lowest DCR?

TLM966411F has the lowest primary and secondary DCR, making it the preferred option when conduction loss and efficiency are the main considerations.

Which series provides the highest saturation current?

TLM966413F generally provides the highest saturation current at equivalent inductance values. It is suitable for designs with large peak currents and demanding transient loads.

What is the main advantage of TLM104613F?

TLM104613F has a narrower package and includes a 90nH model. It is useful for layouts where horizontal PCB space is limited.

Are TLM966411F and TLM966413F interchangeable?

They have the same maximum length and width, but their height, DCR, rated current and saturation-current characteristics are different. The PCB layout, thermal limits and electrical requirements must be verified before replacement.

Can TLM104613F replace TLM966411F?

It is not automatically a drop-in replacement. Although several inductance values overlap, the package dimensions, recommended land pattern, DCR and secondary current capability are different.
