Product News April 17, 2018

 NICHICON CORPORATION has expanded its lineup of compact leaded products with the expansion of available case sizes for the long-life UHW series. This compact, low-impedance series is great for use in LED lighting and general power supplies. As well is adding additional sizes Nichicon has added voltages from 63V to 100V. As a result, the Company has made it possible to make devices even more compact and extend their lifespan.
 This product will be on display at the 33rd Power System exhibition, being held at Makuhari Messe from Wednesday April 18, to Friday, April 20.

Overview/Development Background

 Aluminum electrolytic capacitors are more compact and offer higher capacitance than other capacitors, and the market is calling for even higher levels of capacitance, lower resistance and longer lifespans. Market demand is increasing for capacitors that are smaller and have lower impedance, with the goal of making devices that are more compact and increasing their output.
 In response to these market needs, NICHICON has added φ5 x 11L to φ10 x 12.5L (mm) compact sizes to its UHW series of aluminum electrolytic capacitors and increased guaranteed endurance at 63V to 100V from 10,000 hours on current products to 11,000 hours for φ8 x 15, φ8 x 20L (mm) products. Strengthening the lineup further, we have increased the guaranteed lifespan to 12,000 hours on products φ10 (mm) or larger.

Features

 By optimizing the product design on the UHW series and using an electrolyte that contributes to low impedance and an extended lifespan, we have achieved the industry’s highest level of endurance for low-impedance products for power supplies, at up to 12,000 hours (105°C). Also achieving greater compactness compared to the current UHE series, for a φ10 x 16L (mm) product the UHW series features capacitance of 1,200μF, compared to 820μF, achieving approximately 1.5 times higher capacitance.
Furthermore, the UHW series also achieves an approximate 50% reduction in impedance for a 100V, φ5 x 11L (mm) products. The UHW series is ideal for use in LED lighting and various types of power supplies that require a long lifespan, compactness and low impedance.
