Description

SMD Chip Resistor size 0603 1.6K Ohm

0603 SMD Chip Resistor (1.6KΩ) – Key Specifications

Model Example: RC0603FR-071K6L (Yageo) or equivalent

1. Basic Parameters

• Resistance (R): 1.6KΩ (1600 ohms)
• Tolerance:
  • Standard: ±1% (e.g., F series in Yageo).
  • Cheaper Option: ±5% (e.g., J series).
• Power Rating (P): 0.1W (1/10W) (standard for 0603).
• Max Working Voltage: 50V (typical for 0603).
• Temperature Coefficient (TCR):
  • ±100ppm/°C (for ±1% tolerance).
  • ±200ppm/°C (for ±5% tolerance).

2. Physical Dimensions

• Package Size: 0603 (Imperial) / 1608 (Metric).
  • Length: 1.6mm (0.06″).
  • Width: 0.8mm (0.03″).
  • Height: 0.45mm (typical).
• Termination: Matte Sn (tin) plating (RoHS compliant).

3. Electrical Characteristics

• Current Rating:
  • ~8.8mA (calculated via I=P/RI=P/R​).
• Frequency Response:
  • Effective up to GHz range (parasitic inductance ~0.5nH).

4. Material & Construction

• Substrate: High-purity alumina (Al₂O₃).
• Resistive Layer: Thick-film ruthenium oxide (RuO₂).
• Protection: Epoxy coating (anti-sulfur for harsh environments).

5. Operating Conditions

• Temperature Range:
  • -55°C to +155°C (standard commercial grade).
• Soldering Conditions:
  • Reflow peak: 260°C max (10 sec).
  • Hand soldering: 350°C max (3 sec).

6. Applications

• Pull-up/pull-down resistors (e.g., I²C, GPIO).
• Voltage dividers (with other resistors).
• Signal conditioning (RC filters).
• Consumer electronics, IoT devices.

• Why 0603 Size? 

• Small footprint (saves PCB space vs. 0805).
• Suitable for automated assembly (pick-and-place machines).
• Balances ease of soldering (easier than 0402 for hand soldering).
