1% High precision 25ppm/°C SMD Resistor Metal Film MELF Resistors MM Series

• SMD enabled structure with excellent solderability.
• Conformal multi-layer coating against humidity.
• 5% resistance values are 3-band coded; 2% and below are 4-band coded.

The MM Series Metal Film MELF Resistors are precision surface-mount resistors engineered for electronic circuits that require excellent resistance stability, low temperature coefficient, and dependable long-term performance. With temperature coefficient options of ±25ppm/℃, ±50ppm/℃, and ±100ppm/℃, the MM Series delivers accurate resistance characteristics for industrial electronics and precision electronic assemblies.

Its cylindrical MELF construction supports automated SMD assembly while the conformal multi-layer protective coating improves resistance to humidity. Combined with an insulation resistance of 10,000MΩ minimum, operating temperatures from -55℃ to +125℃, and verified 1,000-hour load life testing at 70℃, the resistor is well suited for applications demanding consistent electrical performance over extended operating periods.
