From Our Factory Floor
Our fan capacitors undergo acoustic noise validation (target: <30 dB) alongside standard electrical QA at our Hosur facility. In internal life-cycle testing, our 2.5 µF fan capacitors demonstrated stable capacitance within ±3% over 30,000 hours — satisfying the extended-life requirement per IEC 60252-1 standard. Every batch is tested for capacitance, dissipation factor (DF ≤ 0.005 @ 50Hz), insulation resistance (>10,000 MΩ·µF), and 2× rated voltage withstand before dispatch.
Testing conducted at NR Capacitor manufacturing facility, Bagalur, Hosur, Tamil Nadu — data on file.

Selection Guide
How to Select the Right
How to Select the Right
Ceiling & Exhaust Fan Capacitor
Follow these 7 steps to specify the correct capacitor for your fan motor application.
-
Identify your fan type and motor specifications
Determine if it's a ceiling fan, exhaust fan, kitchen hood, or industrial ventilator. Check motor nameplate for rated voltage, frequency (50/60 Hz), and existing capacitor µF value.
-
Determine required capacitance (µF)
Residential ceiling fans: typically 2.5–4 µF. Exhaust fans/kitchen hoods: 1–3 µF. Industrial ventilators: up to 6 µF. Replace with exact µF rating — undersizing reduces torque; oversizing causes overheating.
-
Select voltage rating ≥ your supply voltage
Standard Indian supply is 230V AC — use 250V or 330V rated capacitors. For voltage fluctuations or export markets, 400V or 440V provides better surge protection and longer life.
-
Choose MPP film dielectric for silent, efficient operation
Metallized polypropylene (MPP) film gives acoustic noise <30 dB (whisper-quiet), low dissipation factor (≤0.005 @ 50 Hz), and self-healing dielectric for long life. Avoid electrolytic capacitors for fan duty.
-
Verify operating temperature range
Class C: –25°C to +85°C. For kitchen hoods (higher ambient temps) or outdoor exhaust fans, confirm max ambient temperature stays within this range.
-
Choose termination type: wire leads or quick-connect tabs
Wire leads: standard for ceiling fan OEMs. Quick-connect (fast-on) tabs: common for exhaust fans and aftermarket replacement. Confirm your motor's terminal style.
