Industrial / Heat Sinks
SRQ-SLB-11-2
The SRQ-SLB-11-2 is an alternate-configuration variant of the SRQ-SLB-11 series heat sink, adapted for devices with different lead or tab orientations. It shares the same aluminum alloy base material and fin geometry as the SRQ-SLB-11-1 for consistent thermal performance. Applicable in power electronics assemblies, industrial control modules, and custom OEM designs.
Key Features
- Alternate mounting configuration accommodates non-standard or offset device tab geometries
- Shares SRQ-SLB-11 series fin array for equivalent thermal dissipation performance
- Designed for drop-in replacement in layouts where standard hole patterns are unsuitable
- Extruded 6063 aluminum construction with consistent fin pitch across the array
- Anodized finish provides corrosion resistance in humid industrial environments

Frequently Asked Questions
Can the SRQ-SLB-11-2 be used interchangeably with the SRQ-SLB-11-1?
Not directly — the two variants differ in mounting hole position or pattern to suit different device tab geometries. Thermal performance is equivalent, but mechanical fit depends on your specific semiconductor package. Always verify hole spacing and base dimensions against your device datasheet before substituting one variant for the other.
Does the alternate configuration affect the thermal resistance of the SRQ-SLB-11-2?
No. The fin array geometry and base thickness are identical across the SRQ-SLB-11 series. Thermal resistance values are the same between the -11-1 and -11-2 variants. Any difference in effective Rth(j-a) comes from the mounting interface quality and TIM selection, not the heatsink itself.
What industries typically use the SRQ-SLB-11-2?
The SRQ-SLB-11-2 is commonly used in industrial automation, power conversion, and OEM equipment manufacturing where non-standard device footprints are encountered. It is also popular in retrofit and repair applications where the original heatsink is discontinued and a compatible alternate-pattern replacement is needed.
