Frequently Asked Questions
What are the critical specifications for using ERJP03J2R4V in current-sense applications?
The ERJP03J2R4V provides 2.4 Ω with ±5% tolerance, creating 100 mV drop at 41.7 mA and 200 mV at 83.3 mA, ideal for ADC input ranges (0-200 mV). At maximum 0.2 W rating, continuous current reaches 290 mA (0.2 W / 2.4 Ω). The -150 to +400 ppm/°C coefficient (asymmetric design) maintains sensing accuracy across automotive -40°C to +85°C ranges, with only ±0.028 Ω shift end-to-end.
How does the 2.4 Ω value compare to other current-sense resistor options for DC supplies?
Standard current-sense resistors range from 1 Ω to 10 Ω, with 2.4 Ω offering a balanced middle ground. A 1 Ω resistor produces 100 mV at 100 mA (better SNR but higher dissipation); 5 Ω produces 100 mV at 20 mA (lower current, higher impedance). The ERJP03J2R4V's 2.4 Ω suits 50-100 mA DC supplies in IoT modules, delivering <50 mW dissipation at 150 mA and clear signal conditioning.
When should you use ERJP03J2R4V for inrush limiting versus active soft-start circuits?
ERJP03J2R4V works for 12 V / 5 A supplies as a passive soft-start with RC filtering: 2.4 Ω × 10 µF creates 24 µs time constant, limiting inrush to 5 A peak (reduced from 100 A no-load surge). For aggressive inrush suppression below 2 A peak, active soft-start (series MOSFET gate control) is required. Passive resistor limiting dissipates 2-5 W surge energy; acceptable for <1 Hz startup cycles but not suitable for frequent on-off cycling.
What procurement factors should be considered when ordering ERJP03J2R4V in volume?
Panasonic supplies ERJP03J2R4V in 5,000-unit tape reels with standard 8 mm tape. Lead time is typically 2-3 weeks from stock distributors (Digi-Key, Mouser carry 15,000-30,000 units). Factory direct orders of 500,000+ units receive 12-15% discounts with 6-8 week lead time. For prototyping, 100-unit minimum orders at $0.012-0.018 per unit provide cost-effective access without volume commitment.
