Current: 90mA - Within safe limits

🛡️ Fusible Resistor Features:

Dual Purpose: Acts as both resistor and fuse
Circuit Protection: Burns out to protect delicate components
Fire Resistant: Covered with fire-resistant resin layer
Metal Alloy: Can have metal alloy covering for safety
Color Coded: Same color code system as standard resistors
One-Time Use: Must be replaced after it blows like a fuse

⚡ When Fusible Resistors Fail:

Overcurrent: Too much current causes resistor to heat up
Thermal Runaway: Heat causes resistance material to break down
Open Circuit: Resistor "blows" and creates open circuit
Protection: Prevents damage to expensive downstream components
Visual Indicator: Often shows visible burn marks when failed
