Premium 3-in-1 18650 Battery Holder Spacer – Build Your Power Pack Like a Pro
-
Modular Interlocking Design: These spacers feature a clever “tongue and groove” edge, allowing you to snap multiple units together to create a battery pack of any size ($3 \times N$).
-
Superior Heat Dissipation: Unlike taped packs, these spacers provide a small air gap between cells, preventing overheating and extending your battery’s lifespan.
-
High Impact Resistance: Made from durable, heat-resistant ABS plastic that can withstand vibrations and heavy-duty use.
-
Perfect Alignment: Ensures your 18650 cells are perfectly centered for easy spot welding or soldering of nickel strips.
-
Anti-Drop Structure: The secure fit prevents cells from shifting or falling out during the assembly process.

50V 100uF Non-Polarized Electrolytic Audio Capacitor – High-Fidelity Bi-Polar Crossover Component
Key Features & Performance Specs
-
True Bi-Polar Design: No polarity (+/-) constraints! Ideal for Audio Coupling and Speaker Crossover networks where signals reverse direction. -
Pure Signal Transparency: Minimal ESR (Equivalent Series Resistance) ensures your highs stay crisp and your lows remain punchy without “muddying” the mid-range. -
High Voltage Stability: Rated at 50V 100uF, providing a safe overhead for high-output power amplifiers and home theater systems. -
Audiophile Aesthetics: The sleek Gold & Black casing isn’t just for show—it represents a specialized internal construction designed for low-noise performance. -
Universal Compatibility: Perfect for DIY Audio Projects, Vintage Amp Restoration, and Passive Crossover Repairs.

TL494 SOP-16 IC High-Performance PWM Controller for Precision Power Systems
-
🌈 Complete PWM Circuitry: All functions for pulse-width modulation control are integrated on a single monolithic chip.
-
🔄 Dual Output Modes: Supports both Single-Ended and Push-Pull operations, selectable via the output-control pin.
-
🛡️ Dead-Time Control (DTC): Built-in adjustable dead-time provides a safe buffer to prevent power transistor overlap and damage.
-
🧠 On-Chip Error Amplifiers: Includes two high-gain error amplifiers with a common-mode voltage range of $-0.3V$ to $V_{CC}-2V$.
-
⏱️ Adjustable Oscillator: Features a programmable internal oscillator with frequency control via external $R$ and $C$ components.
-
🛑 Double-Pulse Prevention: Internal flip-flop logic prevents double pulsing at the outputs during push-pull operation.
-
🔗 Easy Synchronization: The architecture allows for simple synchronization with other ICs for multi-rail power systems.
-
⚙️ Uncommitted Outputs: Dual output transistors can sink or source up to 200mA each, offering flexible drive options.
