Metal Alloy Low-Resistance Resistor -LR

• Very low resistance value (achievable 0.25m ohm)
• Tight tolerance (standard ±5%,±1% and ±0.5% available)
• High-temperature durability (up to +170℃)
• Low TCR (achievable 15ppm/℃)
• High-current handling capability (>125A)
• High Power density
• Size variety-( 1206 / 2010 / 2512 / 2725 / 2728 )
