Frequently Asked Questions
Common questions about MR370V2 and motor capacitors
What applications use a 2.0µF 370V AC motor capacitor?
This 2.0µF 370V AC motor capacitor serves filtering, timing, and energy storage functions in circuits operating within its voltage and temperature ratings.
Can the MR370V2 handle high-temperature environments?
The MR370V2 is rated for 70°C, which covers standard commercial and light-industrial environments. For installations in enclosed cabinets or hot climates where ambient temperatures exceed 65°C, consider selecting a 90°C-rated alternative for additional thermal margin.
What torque specification should I use for the MR370V2 screw terminals?
Use the torque value specified in the manufacturer datasheet — typically 1.5–2.5 N·m for M5 terminals and 0.8–1.2 N·m for M4 terminals. Over-torquing can crack the terminal seal and allow electrolyte leakage. Use star washers for vibration resistance and re-torque connections after 24 hours of initial thermal cycling in the target application.
What capacitors can replace the MR370V2?
Cross-referencing the MR370V2 requires matching capacitance (2.0µF), voltage (370V AC), temperature rating (70°C), and physical dimensions. ESR and ripple current ratings must also meet or exceed the original spec for reliable operation. Contact our technical team at 800-731-1433 for verified cross-reference options — we maintain compatibility data across major manufacturers.
Should I derate the voltage when using the MR370V2?
Yes. Industry best practice is to operate capacitors at 60–80% of their rated voltage. For the MR370V2 rated at 370V AC, this means designing your circuit to keep the applied voltage below 296V under all conditions including transients. Voltage derating significantly extends capacitor life — each 10% reduction in applied voltage can roughly double the expected service life for electrolytic types.
What is the lead time for the MR370V2?
In-stock items ship same-day when ordered before 3 PM EST, with standard delivery of 2–5 business days within the continental US. If the MR370V2 shows as out of stock, our sourcing team can typically locate high-voltage motor capacitors within 1–2 weeks through our manufacturer and distributor network.
