MC4 Series
High Voltage 4-Resistor SMD DIP Package
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.
F e at u r e s
• Unique terminals allow spacing
between board and resistor
• Design allows multiple configura-
tions
• 2,500 volts max. per resistor
per pack; 10KV total
• Supplied on tape & reel for
automated placement

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.
