MMU 0102, MMA 0204 and MMB 0207 precision thin film

MELF resistors combine the proven reliability of the

professional products with an advanced level of precision

and stability. Therefore they are perfectly suited for

applications in the fields of test and measuring equipment

along with industrial and medical electronics.

FEATURES

 Approved to EN 140401-803

 AEC-Q200 qualified

 Advanced thin film technology

 Superior stability: Class 0.05

 Wide precision range: 10  to 1 M

 Matte Sn termination on Ni barrier layer

 Compliant to RoHS Directive 2011/65/EU

APPLICATIONS

 Test and measuring equipment

 Industrial and medical electronics

Notes

• These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over

operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

(1)

The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the

printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded.
