Product Overview
The 403A is a Heat Sink made of aluminum with black anodized finish. This extruded double-surface heat sink offers stud mounting. With fins oriented vertically in cabinet sidewall applications, the 403 series heat sink is recommended for critical space applications where maximum heat dissipation is required for high-power TO-3 case styles. Forced convection performance is also exemplary with this double surface fin type heat sink. It is suitable for use with the TO-3 devices.
