EVALUATION KIT

evaluation. The PC board is also a good starting point for an

application specific layout. Provided items include: PC board,

heatsink rated at 1.48°C/W, cage jacks, ceramic bypass capaci-

tors, electrolytic bypass capacitors, two values of current limit

resistors with heatsink, a high current I/O screw connection

terminal strip, and spacers. The amplifier is sold separately.

Common hardware such as screws, nuts and user’s preference

for low current I/O connectors are not provided.

this amplifier. Thermal ratings are for optimum mounting in

free air.

Application Note MP108FD

CAGE JACKS

MS11

jacks. The strip can easily be cut to any desired number of

cage jacks. These are mounted directly in a print circuit board.

After soldering, the carrier is pulled off the cage jacks. Use a

spacer between the PCB and the heatsink to avoid short circuits.

THERMAL INTERFACE

A straight edge is useful here. Place amplifier on the heatsink

and with thumbs apply pressure while moving in a circular

motion to insure a void free interface. Insert fasteners and

torque lightly.

Part number MS11 consists of a carrier strip of 30 cage

Apply a thin even layer of thermal grease to the amplifier.
