SFR16S0 datasheet

Description

SFR16S0 is an axial leaded metal film resistor constructed using a homogeneous metal alloy film deposited on a high-grade ceramic substrate. The resistive value is precisely adjusted via a helical trimming process, and the component is encapsulated with a protective lacquer coating, ensuring excellent stability, low noise, and high reliability in various electronic applications.

Features

  • Metal film technology for high precision and stability
  • Compact size: 0204 package (SFR16S series)
  • Low noise performance (≤ 1.5 µV/V for R > 1 MΩ)
  • Excellent temperature stability
  • High reliability due to protective lacquer coating (light-blue)
  • Resistant to cleaning solvents (IEC 60068-2-45 compliant)
  • Compatible with both Pb-free and leaded soldering processes

Construction Details

  • Resistive element: deposited metal alloy film
  • Substrate: high-grade ceramic body
  • Trimming: helical groove for precise resistance adjustment
  • Leads: tinned electrolytic copper, welded to end caps
  • Coating: insulating lacquer for environmental protection

Electrical Characteristics (Typical)

  • Resistance range: typically from a few ohms up to several megaohms
  • Tolerance: commonly ±1%, ±2%, ±5% (depending on variant)
  • Temperature coefficient (TCR): typically ±50 ~ ±100 ppm/°C
  • Rated power: ~0.25W (at 70°C ambient, for SFR16S)
  • Low voltage coefficient and excellent long-term stability

Functional Description

  • Provides precise resistance for current limiting, voltage division, and signal conditioning
  • Low noise makes it suitable for analog and precision circuits
  • Metal film structure ensures minimal drift over time and temperature

Design Notes

  • Prefer metal film over carbon film for precision and low-noise applications
  • Ensure power derating above 70°C ambient
  • Maintain adequate spacing for high-voltage applications
  • Avoid excessive mechanical stress during PCB assembly
  • Consider TCR impact in precision analog circuits

Typical Applications

  • Precision analog circuits
  • Voltage dividers and reference networks
  • Signal conditioning and filtering
  • Audio circuits (low noise requirement)
  • Industrial and consumer electronics

How to Choose This Resistor

  • Select tolerance based on required accuracy (e.g., ±1% for precision)
  • Check power rating vs. actual dissipation with margin
  • Consider TCR for temperature-sensitive designs
  • Choose metal film for stability vs. carbon film for cost-sensitive designs

Alternative / Equivalent Products

  • Yageo MFR series (metal film resistor)
  • Vishay MRS25 series (higher power alternative)
  • KOA Speer MF1/4 series
  • Carbon film resistors (lower cost, higher noise alternative)
