ELM2FM151P25KT
AiSHi LM series lug-terminal capacitor, 150 uF at 315 V, 105 °C with 3000-hour life for high-voltage DC links and solar inverters.
The ELM2FM151P25KT is an AiSHi LM series large-can aluminum electrolytic capacitor rated at 315 V with 150 uF, supplied with a lug (screw) terminal for a busbar or heavy-cable connection. It extends the lug-terminal range to the higher 315 V class, which suits a rectified high-voltage bus with margin for switching overshoot, such as in solar inverters, motor drives and high-voltage supplies. The LM series is a large-capacitance snap-in and lug family rated 105 °C with a 3000-hour endurance, designed for the DC link and bulk capacitance of frequency converters, professional power supplies and inverters. The lug terminal accepts a busbar or heavy cable, so the capacitor carries the high DC-link current and the high ripple current of a power stage without the lead limitations of a PCB part. Because the voltage is higher, the capacitance per can is lower, so a bank of several capacitors is common to reach the required energy. Typical uses include the DC link of a high-voltage motor drive, the bus of a solar inverter and the bulk storage of an industrial converter. Every capacitor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file.
FAE Professional Review
The ELM2FM151P25KT is the 315 V lug-terminal part for higher-bus DC links where a 250 V class would not have enough margin. The capacitance is modest at this voltage, so plan a bank and keep the busbar impedance balanced. Confirm the turn-off overshoot of the switches against the bus design.

Frequently Asked Questions
What projects suit the ELM2FM151P25KT?
It suits designs with a higher DC bus that need a 315 V class with margin, such as high-voltage motor drives, solar inverters and industrial converters. The 150 uF per can means a bank is common to reach the required energy.
Our FAE team can help size the bank.
Lug terminal or snap-in?
The lug terminal connects to a busbar or heavy cable, so it suits the high-current main DC link. A snap-in part mounts directly on the PCB and suits the auxiliary rails and dense boards. Many designs use both.
Our FAE team can help partition the design.
