Nippon Chemi-Con Snap-In Overview

BeiLuo supplies genuine Nippon Chemi-Con snap-in aluminum electrolytic capacitors, the compact parts that mount on a printed circuit board with two or four snap-in terminals for a firm mechanical and electrical connection. A snap-in capacitor fits a board without a clamp, which simplifies assembly and saves space, while still offering high capacitance, high ripple current and long life in a small case. Nippon Chemi-Con's snap-in families include the KMH series, a 105 °C general-purpose range with a 2000-hour endurance and a wide 25 V to 450 V spread, the KHT series with a 105 °C 3000-hour endurance and high ripple, and the TXK series with a 105 °C 8000-hour endurance for long-life designs such as solar and industrial converters. Case diameters from about 22 mm to 35 mm and heights from 25 mm to 50 mm cover a broad range of capacitance and voltage, and the terminal layout is standardized so a part can be dropped into an existing footprint. Snap-in capacitors are common in switch-mode power supplies, solar and storage inverters, industrial power conversion and motor-drive auxiliary stages. 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 terminal layout and estimate lifetime from the case temperature and the applied ripple current.

Frequently Asked Questions

How do I read the snap-in capacitor table?

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

Match the terminal layout to your footprint before you commit.

Why choose a snap-in capacitor over a screw-terminal part?

A snap-in capacitor mounts directly on the PCB with no clamp, which simplifies assembly and saves space, and it still offers high capacitance, high ripple and long life. A screw-terminal part is chosen when the current or the capacitance is beyond what a PCB can carry.

Choose by current, capacitance and mechanical design.

How do I keep the capacitor cool?

Ripple current heats the capacitor, and life depends on the core temperature, so keep the ripple within the rating, space the capacitors for airflow, and keep them away from the hottest components. A cooler capacitor lasts far longer.

Our FAE team can review the layout and the ripple margin.
