TO-126 Heat Sinks

Does heat building up in your TO-126 parts lower their efficiency and risk early failure? Our TO-126 Heat Sinks remove heat quickly, keeping your small components effective and durable. 

Base Material

Aluminum or copper; alloy customization available upon request

Thermal Resistance

2.0°C/W to 15.0°C/W, optimized for TO-126 package efficiency

Heat Dissipation Capacity

3 W to 30 W, suited for TO-126 component power levels

Dimensions

Width: 15 mm to 40 mm; Height: 8 mm to 30 mm; Depth: 15 mm to 50 mm (customizable to fit TO-126 layouts)

Weight

0.015 kg to 0.4 kg, based on material and size for TO-126 integration

Product Description

Rising temperatures in TO-126 packages reduce output and strain systems, increasing breakdown chances. These heat sinks improve performance with close designs, ensuring reliability and strength. 

Fin Design

Vertical fins or stamped fins (straight or flared); fin spacing: 2 mm to 4 mm for airflow efficiency

Mounting Type

Clip-on, screw-mount, or press-fit; designed for TO-126 package attachment

Cooling Method

Passive (natural convection) or active (fan-assisted), depending on TO-126 load and airflow

Operating Temperature Range

-40°C to 120°C, with maximum base temperature rise of 25°C above ambient

Airflow Compatibility

Supports 5 CFM to 50 CFM, effective with case or external airflow

Surface Finish

Anodized aluminum or nickel-plated copper, enhancing durability and heat transfer

Noise Contribution

Silent in passive mode or below 25 dB with active cooling, minimal in TO-126 systems

Durability

Rated for 65,000+ hours under continuous TO-126 operation

Environmental Resistance

Resists dust (IP52 rating) and vibration (per IEC 60068-2-6) in electronic environments

Standards Compliance

Conforms to RoHS, UL 94V-0, and IPC-9592 for TO-126 safety and performance

Thermal Interface Compatibility

Compatible with thermal pads, grease, or tape for secure TO-126 contact

Technical Advantages

Uneven heat spread in TO-126 parts can weaken performance across your small boards. Our TO-126 Heat Sinks use fin spacing from 2 mm to 4 mm, distributing heat evenly for consistent operation. 

Loose cooling fits can raise temperatures and slow your systems under load. Our heat sinks maintain low thermal resistance from 2.0°C/W to 15.0°C/W, securing efficient cooling tailored to your needs.

Industry Applications

Wall Adapters

Removes heat from regulators, keeping devices charging at steady voltage throughout the night without interruptions.

Small Amplifiers

Cools transistors, ensuring audio stays clear and strong across every beat of long playback sessions. 

Fan Controls

Pulls heat off drivers, maintaining smooth fan speeds during every cycle of continuous operation.

Sensor Boards

Takes heat from chips, delivering accurate data readings for every scan over extended use periods.

Switching Units

Manages heat in relays, supporting fast and reliable switching with each flip throughout heavy workloads. 

Portable Lights

Clears heat from circuits, keeping lights bright and steady during every use in demanding conditions. 

Keeping Heat Low for Long Runs

Excess heat in TO-126 parts can cause delays and breakdowns in your tight schedules. Our TO-126 Heat Sinks manage 3 W to 30 W, reducing risks with strong fin designs. 

Unstable cooling can lead to component damage and stop production, raising your expenses. These heat sinks fit sizes from 15 mm to 40 mm wide, ensuring your systems stay cool and active.
