BLM21BD182SH1D - Murata Electronics

BLM21BD182SH1D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BLM21BD182SH1D?
  The recommended land pattern for the BLM21BD182SH1D is a rectangular pad with a size of 2.5mm x 1.6mm, with a non-solder mask defined (NSMD) pad shape. This can be found in the Murata Land Pattern Recommendation document.
• How do I handle the BLM21BD182SH1D's sensitivity to soldering conditions?
  To minimize the risk of damage during soldering, it's recommended to follow the Murata Soldering Conditions guidelines, which specify a peak temperature of 260°C, a soldering time of 3 seconds or less, and a soldering iron temperature of 350°C or less.
• What is the BLM21BD182SH1D's operating temperature range?
  The BLM21BD182SH1D has an operating temperature range of -40°C to +125°C, as specified in the datasheet. However, it's essential to note that the inductor's characteristics may vary outside the recommended operating temperature range.
• Can I use the BLM21BD182SH1D in a high-frequency application?
  Yes, the BLM21BD182SH1D is suitable for high-frequency applications up to 1 GHz. However, it's crucial to consider the inductor's impedance characteristics, self-resonant frequency, and parasitic components when designing high-frequency circuits.
• How do I ensure the BLM21BD182SH1D's reliability in a humid environment?
  To ensure the BLM21BD182SH1D's reliability in a humid environment, it's recommended to follow the Murata Moisture Sensitivity Level (MSL) guidelines, which specify a maximum floor life of 168 hours at 30°C and 60% RH. Additionally, consider using a conformal coating or potting compound to protect the inductor from moisture.
