Part Details for CDRH50D28BT150NP-220MC by Sumida Corporation

The recommended PCB layout and land pattern can be found in the Sumida Corporation's application note or by contacting their technical support. A general guideline is to use a symmetrical layout with a large copper area for heat dissipation and to minimize the loop area to reduce EMI.

The CDRH50D28BT150NP-220MC is designed for high-frequency applications up to 1 MHz. However, its performance may degrade at higher frequencies due to core losses and skin effect. For frequencies above 1 MHz, it's recommended to consult with Sumida Corporation's technical support or consider alternative inductor options.

The SRF of the CDRH50D28BT150NP-220MC is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance and capacitance values. A rough estimate can be calculated using the formula: SRF ≈ 1 / (2 * π * sqrt(L * C)), where L is the inductance and C is the capacitance. For this inductor, the estimated SRF is around 10-15 MHz.

The CDRH50D28BT150NP-220MC has a rated operating temperature range of -40°C to +125°C. While it can tolerate high temperatures, its performance and reliability may degrade above 100°C. For high-temperature applications above 125°C, it's recommended to consult with Sumida Corporation's technical support or consider alternative inductor options with higher temperature ratings.

The recommended soldering profile for the CDRH50D28BT150NP-220MC can be found in the Sumida Corporation's application note or by contacting their technical support. A general guideline is to use a reflow soldering process with a peak temperature of 260°C and a dwell time of 30-60 seconds.
