SMD Resistor 30Kohm (303) (0805) (10pcs)

Description

🔩 SMD Resistor – 30kΩ (303), 0805 Package (Standard Thick Film Chip Resistor – 10 pcs pack) 📌 General Description This is a surface-mount resistor with a resistance of 30kΩ, coded as 303 (which stands for 30 × 10³ = 30,000Ω), in the 0805 footprint. It's typically used in signal conditioning, voltage dividers, pull-up/down configurations, and general-purpose electronics. ⚙️ Key Specifications Specification Value Resistance 30kΩ (30,000 ohms) Resistance Code 303 Package Size 0805 (2.0mm × 1.25mm) Tolerance ±1% (default), ±5% (some types) Power Rating 1/8W (125mW) typical Temperature Coefficient ±100ppm/°C to ±200ppm/°C Operating Temperature -55°C to +155°C Material Thick film (most common) Mounting Type Surface Mount (SMD) RoHS Compliant Yes 📦 Physical Dimensions – 0805 Dimension Size (mm) Length 2.0 mm Width 1.25 mm Height ~0.55 mm 🧪 Typical Applications Voltage dividers Biasing and feedback networks Microcontroller I/O pull-ups/pull-downs Signal filtering with capacitors LED current limiting (low-power LEDs) ✅ Advantages Compact footprint (good for dense PCBs) Precise resistance for signal processing Reliable and low-cost Standard code marking makes ID easy (303 = 30k) ⚠️ Design Tip Keep total power dissipation under 125mW for 0805. For high-accuracy applications, check tolerance and temperature coefficient. Always double-check resistor codes — "303" is 30kΩ, not 3kΩ or 300Ω 😉
