Overview
The P11ZO/P1171 Series datasheet details the specifications and characteristics of Pulse’s shielded drum core surface mount power inductors designed for various applications. They adhere to RoHS compliance, indicating they are manufactured without certain hazardous materials. The inductors feature a maximum height of 6.0mm and a square footprint measuring 12.2mm on each side. The current rating for these components goes up to 13A, with an inductance range between 0.32µH and 750µH. The operating temperature of the series can withstand extremes from -40°C to +130°C.
Electrical Specifications
The inductors are optimized for performance at a benchmark temperature of 25°C. The electrical table provides key characteristics, such as inductance, rated current (Irated), direct current resistance (DCR), self-resonant frequency (SRF), core loss, and the heating and saturation currents. The saturation current is specified with a typical increase of 25% at +40°C. In addition to core loss, DCR is listed in milliohms (mΩ), both giving typical and maximal values where applicable.
Inductance Rating and Tolerance
The datasheet denotes that the inductance at 0A direct current has a tolerance of ±30% on specific part numbers, while a tolerance of ±20% is applicable for all other parts. This indicates a variance in the accuracy of the inductance value, depending on the part number chosen.
Mechanical Specifications
Mechanical details such as the suggested pad layout and the dimensions of the tape and reel for packaging are provided in millimeters and grams. The tape and reel information suggests a packaging format of 500 inductors per reel, facilitating automated assembly processes. The inductors’ dimensions and weight ensure compatibility with standard SMT (surface-mount technology) equipment.
Additional Information
A schematic representation is included to guide the placement and installation of the inductors. Further notes can be found on page 43 of the datasheet, referenced for detailed information. The final section of the first two pages lists contact information for Pulse worldwide, including phone numbers for offices in the USA, Germany, Singapore, Shanghai, China, and Taiwan. The company’s website is also provided for further reference.
