Miniature Aluminium Electrolytic Capacitors

LQ Series

Korea’s No.1 E-cap manufacturer, Samwha Electric has introduced new “LQ” series

It is specially designed for LED market. With 45 years of experience and excellence in customization, Samwha Electric is constantly developing new products to the market.

Electric’s new Snap-in Series

JR & HH Series

In order to provide more options for customers, Samwha Electric has launched two new Snap-in type “JR” and “HH” series in 2021.

“JR” series, an upgrade series of HF series (5,000 hours), has temperature range of -25℃ to 85℃ with the longest lifetime up to 10,000 hours in the lineup. Provided in 400 and 450 volts with capacitance of 56 to 680 μF, it would be an ideal series for applications with requirement of long lifetime at 85℃.

Polymer Hybrid Aluminum Electrolytic Capacitor

YM & YL Series

In consideration of needs of higher ripple current and capacitance at 125℃, Samwha Electric Co., Ltd has launched two new conductive polymer hybrid aluminum electrolytic capacitor “YM” and “YL” series.

“YM” series, a higher ripple current version of YH series (SMD type), has temperature range of -55℃ to 125℃ with the lifetime up to 4,000 hours. Provided voltage range from 25 V to 63 V with capacitance of 47 to 680 μF, it would be an ideal option for the requirement of high capacitance.

Screw Terminal Type Series

GY Series

To improve main 2000 hours at 85℃ screw terminal series GT, development of GY series has been finalized.

Improvement of GT series has been made each year on long life with GF series for 5000 hours’ and with GL series for 20000 hours’ applications. However, GY series is first improvement in both ripple currents and sizes. Available in 450 volts at temperature range of -25℃ ~ +85℃, development of GY series improved highly from GT series. Comparing with 450 volts 3900 μF of GT series GY has size of 5mm smaller and ripple current of 23% higher.

Smallest Radial Series

BN Series

To improve current long life “KJ” series, SAMWHA electric has developed “BN” serie

Main focus on miniaturization and higher ripple current, the new series will lead SAMWHA into new market of smart home.

“BN” series, offered in high voltages of 450 V and 500 V, has high reliability withstanding 12000 hours load life at 105℃. Compared to “KJ” series, it offers smaller size and 10% ripple current increase. For instance, 450 V 150 ㎌ is offered at Φ18 x height 45mm with 1740mA rms in KJ whereas improved “BN” series offers Φ18 x height 40mm with 2000mA rms. This improvement is ideal for long life product required applications.

VP Series

In consideration of demand by Electric Vehicle market, Samwha Electric successfully developed 135℃ guaranteed Aluminum electrolytic capacitor.

This was very first development of such product in Korean market and it led to exclusive approval in Samwha’s domestic EV maket.

“VP” series is developed with low resistance high temperature electrolyte and high efficient raw material. It has high reliability in temperature range of -40℃ to +135℃. Additionally, it has low rate of capacitance change at high voltage and temperature which offers electrical reliability as well as long lifetime. Lower resistance at high temperature provides help to minimization and lifetime extension of circuits and it makes “VP” series ideal for regenerative brake system and power supply of electric vehicles.

Ideal Conductive Polymer Hybrid Series for 5G

Conductive Polymer Hybrid Series for 5G

In order to follow the development of 5G network service, Samwha Electric has developed ideal series for 5G market.

Most suitable for 5G network devices, it has least influence of high and low temperatures. With Korea becoming first country in the world to have more than 10 million 5G users, most mobility base station, which endure large temperature range and reliability in running for 24 hours per day, required improvement.
