Push Pin Heatsinks

Push Pin Heatsinks

The CS946 series offers a broad range of standard black anodized aluminum pin fin heatsinks. The Push pin attachment provides enhanced reliability where vibration is a concern.

Features and benefits:

  • Spring load maintains even pressure onto the chip
  • High efficiency pin fin for low pressure drop
  • Two fin heights are offered to support space limitations and thermal challenges
  • Omi-directional airflow to maximize heat dissipation
  • Re-workable
  • Offered with a phase change interface material to maximize heat transfer
  • Off- the shelf products

LFM Values = Linear Feet Per Minute ( air flow).
