Technical Requirements (for MF51-104F3950(B))

  • Zero Power Resistance: R25: 100K1%
  • B25/50 Value: 3950K1%
  • Leads: 0.25 Magnesite wire
  • Encapsulation: Glass shell package
  • Compliance: Meets environmental protection requirements: RoHS

Installation & Use Precautions

  • Application: Temperature measurement and control.
  • Avoid excessive current that may cause self-heating and measurement errors.
  • When soldering, maintain at least 2mm distance from the glass seal head. Soldering temperature should be below 360, and time less than 3 seconds.
  • If leads are bent, the bending point should be more than 2mm from the glass shell to prevent damage.
  • Storage Temperature: -1040.
  • Storage Humidity: 75% RH.
  • Avoid storage in environments with corrosive gases or direct illumination.
  • After opening packaging, reseal for storage. Storage period is 1 year. Products exceeding the storage period can be re-tested against standard requirements and used if compliant.
  • When using heat-shrink tubes, avoid using a hair dryer. Recommended method: place the product with the heat-shrink tube into a constant-temperature oven and heat shrink at 110 for 10-12 minutes.
