CapXon Radial Leaded Capacitors Overview

BeiLuo supplies genuine CapXon radial leaded aluminum electrolytic capacitors, the through-hole parts with two straight leads that mount on a printed circuit board in a compact footprint. A radial leaded capacitor offers a wide range of capacitance and voltage in small case sizes from about 4 mm to 18 mm in diameter, which suits dense control boards, power supplies and instrumentation where space is at a premium. CapXon's radial families include the KM series, a 105 °C general-purpose range rated 2000 hours with a broad 6.3 V to 450 V spread, the KY series, a 105 °C slim high-voltage range rated 250 V to 450 V for height-limited designs, and the LE series, an ultra-long-life 105 °C range rated 12000 hours for equipment that must run for many years, such as solar, industrial and lighting converters. The leads fit standard 2.5 mm and 5 mm hole spacings, so a part drops into a common footprint, and the operating temperature range is usually -40 °C to +105 °C. Radial leaded capacitors are common in switch-mode power supplies, LED drivers, industrial control boards, instrumentation and low-power converters. Every capacitor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you size capacitance and ripple, choose the lead spacing and estimate lifetime from the case temperature and the applied ripple current.

Frequently Asked Questions

How do I read the CapXon radial capacitor table?

Capacitance and Voltage set the energy and the voltage class, Case Size the board footprint, and Endurance the life at the rated temperature and ripple. Temperature confirms the grade.

Match the lead spacing to your board before you commit.

Which radial series should I choose?

The KM series is a general-purpose 105 °C choice for most boards, the KY series is a slim high-voltage part for height-limited designs, and the LE series is the ultra-long-life choice for equipment that must run for many years.

Choose by voltage, life and size.

How do I get the longest life from a radial capacitor?

Aluminum electrolytic lifetime roughly doubles for every 10 °C reduction in core temperature, so keep the capacitor cool, keep the ripple within the rating and avoid placing it next to a hot component. The LE series already starts from a 12000-hour endurance.

Our FAE team can estimate the lifetime at your conditions.
