| Features: |  |
| ◆ 50 Watt @ 25°C Case Temperature Heat Sink Mounted. | |
| ◆ TO-220 Style Power Package. | |
| ◆ Molded Case for Protection and Easy to Mount. | |
| ◆ Isolated Case. | |
| ◆ Low ohm value. | |
| Electrical Characteristics Specification | Applications: |
| ◆ Operating Voltage:350V Max. | ◆ Non-inductive design for high frequency. |
| ◆ Dielectric Strength: 1800VAC | ◆ Pulsing applications. |
| ◆ Insulation Resistance: 10GΩ min. | ◆ UPS. |
| ◆ Working Temperature Range:-65°C to +150°C | ◆ Voltage Regulation. |
| ◆ Resistance Value < 1Ω is Available | ◆ Switching Power Supplies. |
| ◆ Lead Material: Tinned Copper |
| ◆ Maximum Torque: 0.9 N-m |
| ◆ Without a Heat Sink, When in Free Air at 25°C, the TR50 is Rated for 3W. |
| ◆ The Case Temperature is to be used for the Definition of the Applied Power Limit. |
| ◆ The Case Temperature Measurement Must be Made with a Thermocouple Contacting the Center of |
| the Component Mounted on the Designed Heat Sink. |
| ◆ Thermal Grease Should be Applied Properly. |
