EKMH250VSN183MR40T
Nippon Chemi-Con KMH snap-in capacitor, 18000 uF at 25 V, Ø30 x 42 mm, 105 °C for low-voltage hold-up and filtering.
The EKMH250VSN183MR40T is a Nippon Chemi-Con KMH series snap-in aluminum electrolytic capacitor rated at 25 V with 18000 uF, in a case of about 30 mm diameter by 42 mm long. The KMH series is a 105 °C general-purpose snap-in range with a 2000-hour endurance and a wide voltage spread, and it is a common choice for low-voltage bulk capacitance where a large capacitance is needed in a single compact part. A snap-in capacitor mounts directly on the printed circuit board with two or four terminals, giving a firm connection without a clamp, and the standardized terminal layout drops into a common footprint. The 25 V rating suits low-voltage rails and 12 V or 24 V buses, and the very high 18000 uF capacitance makes the part useful for hold-up, filtering and transient support in power supplies and low-voltage converters. The operating range is -40 °C to +105 °C, which covers most industrial and consumer enclosures. Typical uses include the output bulk capacitance of a low-voltage supply, a 24 V industrial bus and the filtering of a motor-drive auxiliary rail. 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 and estimate lifetime from the case temperature.
FAE Professional Review
The EKMH250VSN183MR40T packs 18000 uF into a compact 30 mm can, which is ideal for low-voltage hold-up and filtering where board space is tight. It is a general-purpose 105 °C part, so verify the ripple margin and the case temperature for your duty. The snap-in terminals keep assembly simple, and the standardized layout makes substitution easy.

Frequently Asked Questions
What projects suit the EKMH250VSN183MR40T?
It suits low-voltage rails and 12 V or 24 V buses that need a large capacitance in a compact part, such as hold-up and filtering in power supplies and low-voltage converters. The 18000 uF capacitance fits a 30 x 42 mm snap-in can.
Confirm the ripple margin for your duty.
How much ripple can it handle?
The rated ripple current depends on the case temperature and the frequency, so check the datasheet ripple rating at your conditions and keep within it. At low voltage and high capacitance the ripple rating is generous, but a hot layout still reduces life.
Our FAE team can confirm the ripple margin.
