TCH35P220RJE - Ohmite

TCH35P220RJE Frequently Asked Questions (FAQs)

• What is the thermal resistance of the TCH35P220RJE?
  The thermal resistance of the TCH35P220RJE is typically around 10°C/W, but this value can vary depending on the specific application and mounting method. It's recommended to consult with Ohmite's technical support or refer to the manufacturer's application notes for more information.
• Is the TCH35P220RJE suitable for high-frequency applications?
  The TCH35P220RJE is a thick-film resistor, which can exhibit some high-frequency limitations. While it can be used in high-frequency applications, its performance may degrade above 100 MHz. For high-frequency applications, it's recommended to consider Ohmite's thin-film resistors or other specialized high-frequency resistor products.
• Can the TCH35P220RJE be used in high-temperature environments?
  The TCH35P220RJE has a maximum operating temperature of 155°C, but its power rating decreases as the temperature increases. For high-temperature applications, it's essential to derate the resistor's power according to Ohmite's derating curves. Additionally, the resistor's reliability and lifespan may be affected by prolonged exposure to high temperatures.
• Is the TCH35P220RJE compatible with lead-free soldering processes?
  Yes, the TCH35P220RJE is compatible with lead-free soldering processes. Ohmite's resistors are designed to meet the requirements of lead-free soldering, and they can withstand the higher temperatures associated with these processes.
• What is the recommended land pattern for the TCH35P220RJE?
  The recommended land pattern for the TCH35P220RJE can be found in Ohmite's datasheet or application notes. In general, a land pattern with a minimum pad size of 0.12 inches (3.05 mm) and a maximum pad size of 0.15 inches (3.81 mm) is recommended. It's essential to follow the recommended land pattern to ensure proper soldering and to prevent thermal issues.
