CN50-20B - 50 mm Round x 20 mm High Alpha Heat Sink - 7.3 °C/W 50 mm Round x 20 mm High Alpha Heat Sink - 7.3 °C/W
The CN50-20B Alpha heat sink offers a natural convection thermal resistance rating of 7.3 °C/W within a 50mm round footprint. The round shaped pins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs. 
CN50-40B - 50 mm Round x 40 mm High Alpha Heat Sink - 5.2 °C/W 50 mm Round x 40 mm High Alpha Heat Sink - 5.2 °C/W
The CN50-40B Alpha heat sink offers a natural convection thermal resistance rating of 5.2 °C/W within a 50mm round footprint. The round shaped pins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs. 
CN50-45B - 50 mm Round x 45 mm High Alpha Heat Sink - 4.9 °C/W 50 mm Round x 45 mm High Alpha Heat Sink - 4.9 °C/W
The CN50-45B Alpha heat sink offers a natural convection thermal resistance rating of 4.9 °C/W within a 50mm round footprint. The round shaped pins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs. 
CN50-15B - 50 mm Round x 15 mm High Alpha Heat Sink - 8.3 °C/W 50 mm Round x 15 mm High Alpha Heat Sink - 8.3 °C/W
The CN50-15B Alpha heat sink offers a natural convection thermal resistance rating of 8.3 °C/W within a 50mm round footprint. The round shaped pins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs. 
CN50-25B - 50 mm Round x 25 mm High Alpha Heat Sink - 6.6 °C/W 50 mm Round x 25 mm High Alpha Heat Sink - 6.6 °C/W
The CN50-25B Alpha heat sink offers a natural convection thermal resistance rating of 6.6 °C/W within a 50mm round footprint. The round shaped pins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs. 
CN50-30B - 50 mm Round x 30 mm High Alpha Heat Sink - 5.9 °C/W 50 mm Round x 30 mm High Alpha Heat Sink - 5.9 °C/W
The CN50-30B Alpha heat sink offers a natural convection thermal resistance rating of 5.9 °C/W within a 50mm round footprint. The round shaped pins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs. 
CN50-35B - 50 mm Round x 35 mm High Alpha Heat Sink - 5.5 °C/W 50 mm Round x 35 mm High Alpha Heat Sink - 5.5 °C/W
The CN50-35B Alpha heat sink offers a natural convection thermal resistance rating of 5.5 °C/W within a 50mm round footprint. The round shaped pins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs.
