PRODUCT UPDATE 25 www.power-mag.com Issue 2 2024 Power Electronics Europe Kyocera has released two new series of snap-in aluminum electrolytic capacitors: the SNA Series and SNL Series. SNA and SNL Series snap-in aluminum electrolytic capacitors claim to deliver high-reliability, high-voltage, and high-CV performance over long lifetimes. In addition, both series are lead-free compatible and RoHS compliant, rated for temperatures extending from -25°C to 105°C, and ideal for use in commercial and industrial applications including frequency converters, solar inverters, power inverters, energy storage systems, and power supplies. The SNA Series snap-in aluminum electrolytic capacitors also claim to exhibit high ripple current capabilities, long lifetime performance, and endurance of 5,000 hours at 105°C. They are currently available with three rated voltages (250, 420, and 450VDC), 24 case sizes spanning 22mm x 25mm to 35mm x 50mm (D x L), and capacitance values extending from 82µF to 1,500µF ±20%. Likewise the SNL Series snap-in aluminum electrolytic capacitors claim to exhibit endurance of 3,000 hours at 105°C. They are currently available with eight rated voltages (160, 200, 250, 350, 400, 450, 500, and 550VDC), 36 case sizes spanning 22mm x 20mm to 35mm x 60mm (D x L), and capacitance values extending from 68µF to 2,200µF ±20%.

Housed in a metal IP65 enclosure with baseplate conduction cooling, the ECD1000A series claims it delivers 1000W and can be used with a baseplate operating temperature range of -40 up to 75 degrees C. For extremely demanding applications the ECD1000A is mechanically ruggedized according to the MIL-STD-810H standard and interior boards and components are protected with a conformal coating. The product may be equally well electrically ruggedized to withstand harsh transients and meet demanding EMC performance levels as required for most common defense and the more demanding industrial applications, according to the MIL-STD- 461 CE102 / RE102 and meeting the MIL-STD-1399-300. The power supply operates with a wide universal input range from 85 to 305VAC with power factor correction (PFC). Designed for high availability, short time-to-market and to meet commercial and military off-the-shelf (COTS/MOTS) business models, the ECD1000A is available in a 28VDC output voltage version, however the series also includes 500W and 700W versions with 12VDC and 28VDC output voltages for use in lower power distribution systems. Power supplies for defence and harsh environments Many defense applications require power supplies to operate with limited or no ventilation cooling. In this respect, we are referring to those operating in harsh environments where electronic equipment is installed in a sealed box, such as radio communication systems subject to adverse weather conditions, outdoor surveillance and access control, and indoor equipment with very strict audible noise restrictions. In addition to environmental requirements, reliability and cost of maintenance are motivating systems designers not to use fans and blowers, privileging conduction cooling enclosed in a box that offers an ingress protection level of IP65 (Dust tight and protected against water jets). Conduction cooling requires very specific building practices and the ECD1000A has been designed to guarantee optimal heat transfer from the dissipating components to the baseplate, delivering a high level of performance within an operating temperature of -40 to 75 degrees centigrade at the baseplate. Depending on the assembly method and the overall cooling conditions, a derating may apply as specified in the technical documentation.

The series claims it impresses with a wide inductance range and a high saturation current with an extremely small size. Further advantages are the special inner winding and the fully magnetically shielded design. furthermore the inductor series claims it works reliably at operating temperatures from -40 °C to 125 °C and is suitable for use in a wide range of applications, e.g. for voltage regulator modules, DC/DC converters, embedded PCs, or switching power supplies. The inductors are available in tape & reel packaging for quick and cost-effective assembly For more information visit: www.rutronik24.com. Tiny, fully shielded SMD power inductors
