The recommended land pattern for ESR18EZPJ221 can be found in ROHM's Chip Resistor Land Pattern document, which provides guidelines for pad size, spacing, and layout to ensure reliable soldering and performance.
While the datasheet specifies an operating temperature range of -55°C to 155°C, ROHM recommends derating the resistor's power rating at high temperatures. For example, at 125°C, the power rating is reduced to 50% of the maximum value. Consult ROHM's application notes for more information.
Yes, ESR18EZPJ221 is designed for high-frequency use, with a self-resonant frequency of approximately 100 MHz. However, the resistor's impedance may vary at high frequencies due to parasitic inductance and capacitance. Consult ROHM's high-frequency resistor application notes for more information.
While ESR18EZPJ221 is designed to be moisture-resistant, it's still important to follow proper handling and storage procedures to prevent moisture absorption. ROHM recommends storing the resistors in a dry, cool place, and avoiding exposure to high humidity or water.
ROHM recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a cooling rate of 4°C/second or less. Consult ROHM's soldering guidelines document for more information.
