Ohmite’s MC4 Series offers 4 high
voltage SMD resistors in a single DIP
package, supplied on tape and reel for
automated placement. Each resistor pro-
vides a rating of 0.75W with a maximum
voltage of 2500 VDC. Designers can
specify up to 4 different resistor value/
tolerance combinations and connect then
individually, in series, or parallel to derive
countless results. The flexible S-Bend ter-
minals provide solder joint integrity while
leaving space between the resistor pack
and the PCB. Standard parts are available
in single resistance values for immediate
delivery.

Solder
Silver solder is recommended for
MC4 resistors. Leaching of the
silver in the termination will occur if
non-silver solder is used. 60/40 tin-
lead solders are not recommended
for use with the MC4 product.
