Since 1994, Ametherm has provided the most reliable and effective inrush current limiting solutions available.

Ametherm – Inrush Current Limiters and Thermistors

They have newly developed the MS 35 Series Inrush Current Limiters that are capable of handling up to 900 joules of energy and 50 amperes of steady state current. This will be a useful component to consider for power electronics engineers in the design of power supplies and inverters.

Protect An Inverter From Inrush Current

A common failure of inverters is overloading the inverter due to inrush current . This is due to the fact that most inverters are designed with a minimum amount of resistance to increase their efficiency and minimize losses due to heat.

Surge-Gard Inrush Current Limiters

NTC Thermistors – Negative Temperature Coefficient (NTC) thermistors are thermally sensitive semiconductor resistors which exhibit a decrease in resistance as absolute temperature increases.

SURGE-GARD Inrush current limiting devices have specially formulated metal oxide ceramic materials. These devices are capable of suppressing high inrush current surges.

Nippon Chemi-Con. Products multilayer ceramic capacitors, film capacitors, metal oxide varistors, choke coils, optomechatronics and Aluminum electrolytic capacitors.

Aluminum Electrolytic Capacitors – Nippon

New Technologies – Hgh capacity electric double layer capacitors and newly designed decoupling device Proadlizer. Electric Double Layer Capacitor (EDLC) or SuperCapacitor.

They have a range of Supercapacitors upto 2500F at 2.5V and Modules like 400F at 15V. There are two types Prismatic and Cylindrical. In comparison to batteries, multi-million cycles of charge-discharge is possible.

DLCAP - Electric Double Layer Capacitor - Nippon

DLCAP – Electric Double Layer Capacitor – Nippon

Another feature is the high current charge-discharge ability, useful in many Industrial and Automotive Applications. A high charge-discharge efficiency makes an output efficiency of around 95% possible. These capacitors have become an useful part of Alternative Energy Electronics and Energy Harvesting. They also have applications in Electric and Hybrid Vehicles.

TDK – Electronic components and Materials

TDK was founded in Japan on 7 December 1935 to manufacture iron-based magnetic material ferrite, which had been recently invented by Yogoro Kato and Takeshi Takei. In 1952 they began production of magnetic tapes, with compact cassette tapes following in 1966; it is for these that the company is most widely noted
