MMU 0102 HF, MMA 0204 HF, MMB 0207 HF

Vishay Beyschlag

High Frequency MELF Resistors

FEATURES

• Speciality product for RF applications

• Low-inductance non-helical trimmed product

• Suitable for more than 10 GHz

• Force fitted steel caps, tin plated on nickel barrier

• Pure Sn termination on Ni barrier layer

• Compatible with lead (Pb)-free and lead containing

soldering processes

• Lead (Pb)-free and RoHS compliant

APPLICATIONS

• Telecommunication equipment

• Industrial electronics.

MMU 0102 HF, MMA 0204 HF and MMB 0207 HF speciality

thin film MELF resistors for RF applications are the perfect

choice in high frequency circuit designs where the

impedance change due to the parasitic inductance of regular

and professional resistors can not be accepted. Typical

applications are in the fields of telecommunication

equipment and industrial electronics.

Failure rate

Note: 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. Furthermore, a

high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board

materials may be required to maintain the reliability of the assembly.

²⁾Specified power rating requires dedicated heat-sink pads.
