Choke coils meet demanding automotive applications

Now available in Europe through TTI are Panasonic’s power efficient LP-Series power choke coils and ZE-Series Conductive Polymer Hybrid Aluminum SMD technology capacitors featuring a high ripple current (up to 2.0A) and a low ESR value. Rugged LP series power choke coils offer inductance stability over a broad temperature range, have low power losses and a low audible (buzz) noise.


The products use a metal composite core and are ideal for demanding automotive applications, where high reliability and compact size is needed.

Application examples are noise filters for various drive circuitry requiring high temperature operation and peak current handling capability.

LP series products benefit from a low profile (3mm and 4mm maximum height) and feature high heat resistance (designed for operation up to +155°C and for peak temperatures of +180°C).

A newly developed integral construction results in very good vibration resistance under severe reliability conditions and further improves the reliability.

Combining the advantages of electrolytic capacitors with those of solid Polymer Capacitors, highly reliable and versatile ZE series hybrid capacitors offer low leakage current and long life in combination with low ESR (20mΩ) in miniature case sizes.

The ultra-high temperature products have a high endurance of 2,000 hours at 145°C, are vibration proof (up to 30G), and are ideal for a broad spectrum of automotive applications including input/output filtering in power converters and voltage regulators, power and battery decoupling and clock circuitry.
